The square compass measures 6.8 cm each side forming a sundial with a bird-shaped gnomon for lattitudes 40 to 60 degrees.
The silvered compass is divided into 360 degrees and with cardinal points.
This dial has the rare peculiarity of having been, at the time, covered with long-grained morocco decorated with gilded decoration.
The instrument is not signed but French and can be dated from the Napoleonic period or just after.
Small lack at the hook used to keep the instrument closed, small stain in morocco under the dial, otherwise good condition.
